I can create my geometry the way I always have and add tolerances
to the model dimensions i used when I sketched my features.
however it seems if I wish to add geometric tolerances etc to my model for the purpose of model based definition I need to swith to dimxpert.
The dimexpert dimensions become almost an add on to the dimensions I have already made in my sketch based definition and dimensioning scheme,They dont actually control the model
Nope, not missing anything. DimXpert allows for you to do a check for tolerance stackups in you assemblies. There's a tutorial that'll clarify things for you.

Jeff they seem to be reference dimensions not the actual sketch dimension if for example I draw a disc of material 90 diameter +/-0.1 and 10 thick +/-0.25 I set the tolerance in the model sketch I can reuse this in the drawing.
I get going with dimxpert ,set primary ,set secondary datums and sure it gives me 90 and 10 but not the tolerance I set in the model.Sure I can set the tolerance I want in the dimxpert dimension but it seems the dimxpert model definition can be different to the version which and so I have to manually tolerance the thing
Im wondering if annotation view is better as it reuses the tolerances I embed in the model but I cannot add geometrical toleraces or datums to it other than in the drawing
I find the Dimxpert to be pretty useless. But then again I do not make anything that is a box or a sphere. All my stuff is molded so it has draft. Anyway, from my limited testing it allows you to put GD&T dimensions on the 3D solid so they can be viewed in an Edrawings file of the solid or in an isometric view on a 2D drawing. You can also use it to do a tolerance stack up analysis for you but unless you have a lot of parts in your stack up it would probably just be easier to do it in excel.
They are reference dimensions just like the ones you create in 2D drawings but if they are put on the solid you can import them into your drawings as well.
GRF and all others thanks for the replies it seems it's a half solution to a problem .I'm not bashing it but now I have a handle on it it doesn't,t quite do what I was thinking it did and the reasoning is quite simple but ibthink it does take a while to get rid of the old way some of us work.
